I'm not sure how you got that out of what I said.

I'm saying:

- pick a point in jdk/jdk for your backport to begin,
   e.g., jdk-12+24 snapshot
- grab the relevant files (hopefully there won't be
   much overlap with non JFR changes)
- do the backport to OpenJDK8u
- find the original changeset for the JFR port to give
   you the first bug ID
- find subsequent JFR bug fix changesets to give the
   next bug IDs
- list all the bug IDs in your single changeset for the
   JFR backport to OpenJDK8u.

One changeset that lists multiple bug IDs. Not individual
backports of each bug fix. Will you miss something in the
list? Maybe or maybe not.
